FILLING-CARRIER FOR FEELEYR-LOOMSILQ SPECIFICATION forming part of Letters Patent No. 760,627, dated May 24, 1904.

To all whom it may concern; 7

Be it known that I, OSCAR E. HoLDR DeE,

a citizen of the United States, and. a resident of New Bedford, county of Bristol, State of- 5 Massachusetts, haveinvented an Improvement in Filling-Carriers for Feeler-Looms, of which the following descrlption, 1n connection w1th the accompanylngdrawlngs, 1s a specification,

like characters on the drawings representing 1 like parts.

Certain types of looms equipped with mech-- anism to automatically replenish the. running ifilling are also provided with means to eflect' filling replenishment prior to 'completeexhaustion of the filling in the running shuttle, and such looms are technically termed feelers Thename is derived from a member which intermittently engages and feels the filling in the shuttle, the construction and ar-. rang'ement being such that filling replenish-5 looms.

ment is effected while-there yet remains a small portion of filling on the filling-carrier 0r bobbin in the shuttle. aIt requiresconsiderable-labor toremove this'remaining filling 5 from the bobbin, such removal being necessary before a fresh yarn load can be spun on the bobbin. Sometimes the" remaining portion of'yarn can be pulledofl the bobbin by the fingers, but more frequently a knife has 3 to be used, and this not only requires time,

but damagesthe bobbins, the latter ordinarily being made of wood. In my present invention I have overcome these objections by slipping onto the bobbin a thin and readily-col' lapsible tube before the spinning operation begins, the yarn beingv spun over the tube. v As the tube is short, thebutt of, the'yarn mass is spun thereupon, it being well known that the action of the feeler is directed to such After the bobbin has been ejected from the shuttle at time of filling replenishment the tube can bequickly slid off the bobbin, and the yarn remaining thereon is removed by pressing or squeezing the tube slightly with the fingers to thereby collapse it suflicientlyto permit the bunch of yarn-to slide ofl easily. The tube is then put back on the bobbin, which is ready to have another yarn load spun thereupon.

ment of the tube when the bobbin is in the 1 shuttle. I have accordingly provided means to prevent such movement, while no material resistance is offered to removal of the tube fromthe-empty bobbin. l

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims. 1

Figure 1 is a" view in elevation of a'fillingcarrier embodying one form of my invention in readiness for the yarn load to be spun thereupon. Fig. 2 is a similar view, but showing the tube with a portion of yarn thereon partly pulled off the bobbin, and showing one form of retaining means to prevent improper movement of thetubeon-the bobbin. Figs. 3 and 4: are views 'in' elevation of filling-carriers provided with other forms of retaining means for the tube, the tube in each case being so positioned as to clearly show the retaining means. Fig. 5 is a longitudinal sec,- tional detail on the line 5 5, Fig. 1; and Fig. 6 is an end view of a tube collapsed sufficiently to permit the ready removal of the yarn therefrom.v

Referring to the drawings, the bobbin 1 has a head EZ, shown asprovided with annular projections or rings 3.to be engaged by holdingjaws in the shuttle, a construction which is largely usedin automatic looms of the Northrop typesuch, for instance, as forms the subject-matterof United States Patent N o; 529,940'and others. Adjacent the head the body or barrel of the bobbin is made cylin 'drical, as at 4;, the cylindrical portion beinglongenough'to sustain that part of the yarn mass withwhich the feeler cooperates. A

short tube 5 of thin and readily-collapsible The filling-carrier (shown in Fig. 1) is ready to have the yarn load spun upon it, the butt of the yarn mass beinglaid upon the tube, and if the spinning begins with a bunch of yarn suchbunch is laid upon the tube.

When the filling-carrier has been ejected from the shuttle by the operation of the filling-replenishing mechanism, the attendant draws off the tube from the bobbin with the small portion y of yarn thereon. (See Fig. 2.) The tube is then slightly squeezed or pressed between the fingers to collapse it, as shown in Fig. 6, and the yarn thereon can then be easily slid off, after which the tube is replaced upon the bobbin.

It is necessary, of course, to prevent any rotation of the tube on the bobbin during spinning and also to prevent any accidental movement of the tube when the bobbin is in the shuttle, and I have shown several forms of retaining means to prevent such movement. One of the simplest and at the same time thoroughly-effective forms is shown in Figs. 1, 2, and 5.

Referring to Figs. 2 and 3, a shallow annular groove 6 is made in the part 4: of the bobbin near its outer end, and a piece of worsted or other soft textile material 7 is tied in the groove with its ends 8 left long. When the tube is slipped into place, it compresses the worsted between it and the cylindrical part of the bobbin, the frictional engagement of the worsted with the tube preventing any turning or other movement thereof on the bobbin.

The worsted offers no material resistance to the removal of the tube when pulled off by the fingers, while it serves as an eflicient device to prevent accidental or improper movement thereof.

In Fig. 3 the annular groove 9 in the cylindrical part 4 of the bobbin is intersected by a longitudinal groove 10, and a piece of light wire 11 is bent around in the groove 9 and one end is carried down the groove 10, as at 12. This end 12 is bent out slightlybeyond the surface of the portion 4 of the bobbin to contact with and frictionally hold the tube when in place, the grooves serving to hold the retaining device in place.

If desired, either or both ends of the wire can be bent inward and forced into the material of the bobbin.

In the form ofretaining device shown in Fig. 4 the groove 13 is made nearer the center of the part 4 of the bobbin and a piece of wire 14 is bent into ring shape and slipped thereinto, the wire being so bent as to extend slightly beyond the surface of the part 4 to engage the tube and prevent improper movement thereof on the bobbin.

My invention is not restricted to the precise construction shown and described, as the same may be varied or modified in diiierent particulars without departing from the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A filling-carrier for use in feeler-looms, comprising a bobbin, a readily collapsible and removable tube slidable thereon to support the butt of the yarn mass when spun thereupon, and means to automatically cooperate with and prevent accidental movement of the tube on the bobbin.

2. A filling-carrier for use in feeler-looms, comprising a bobbin, a short collapsible tube slidable thereon and adapted to support the butt of the yarn mass when spun thereupon, and friction means to prevent accidental movement of the tube on the bobbin.

3. A filling-carrier for use in feeler-looms, comprising a bobbin, a tube adapted to he slid upon the bobbin to receive the butt of the yarn mass in the spinning operation, and a device on the bobbin to frictionally engage said tube and prevent accidental movement thereof upon the bobbin.

4. A filling-carrier for feeler-looms. comprising a bobbin having a head and an adjacent cylindrical portion, a cop-tube adapted to be slid upon said portion of the bobbin to receive the butt of the yarn mass in the spinning operation, and a frictional retaining device on the bobbin to interiorly engage and retain the cop-tube from accidental movement thereon.

5. A filling-carrier for feeler-looms, comprising a bobbin having a cylindrical portion near its head, a short tube adapted to be slid onto said cylindrical portion to support the butt-end of the yarn mass in the spinning operation, and a flexible retaining device on the bobbin to interiorly engage and by frictional contact prevent accidental movement of the tube on the bobbin.

6. A filling-carrier for foeler-looms, comprising a bobbin having a cylindrical portion near its head, a short tube adapted to be slid onto said cylindrical portion to support the butt-end of the yarn mass in the spinning operation, and a soft textile retaining member on the bobbin to engage the interior of the tube and by frictional engagement therewith prevent its accidental movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
